I don't really have any of the symptoms described above, but it would be interesting to check the timing on my newly acquired 1988 F250 IDI 7.3 since I know nothing of its history. Odometer reads 27,000 but I have no idea how many other times it may have done so.I own a meter, I toss it on normally every spring just to check. Takes 5 mins to check
Might give R&D IDI Performance a call - they're over in Maple Valley.I live in western Washington State. I'd like either have my timing checked (who'd be reputable to do this?) or, preferably, to check it myself if possible.
